About Grainhouse
Grainhouse edits photos the way a lab would. Pick a film stock, then adjust grain, fade and warmth until the picture looks like it came back from the developer.
Edits are saved as a recipe, so the original is never changed and one look can be applied to a whole trip in a single pass.
What it does well

Colour and black-and-white looks, each with its own grain structure.
Grain engine
Grain is generated per photo at full resolution, so it holds up in prints.
